Everything has a smell or taste that is characteristic for that uniqe thing or human. There is an uniquely essence for each living such as human or dead material, as eg. stone. There are some smell or taste we do not appreciate and those essences we avoid. Sometimes we do not only avoid those essences but we try to eliminate them. Trying to eliminate things or behaivor at other humans, that we do not like is a manifestation of disrespect of things that we do not understand.
It is a proof of a great sense, to respect those things that we do not understand. When we manage to reach that point, there is also a possibility to find the core, motive and the purpose of each thing or human. Simply to find each truth.
